表面と同一面となるまで凹部に収納される。In the window opening / closing device, the window is closed if the wire is wound around the winding mechanism and the winding mechanism is engaged with the ratchet mechanism. At this time, for example, the window is constrained in the opening direction by at least one of the dead weight of the window and the biasing force of the opening mechanism that biases the window in the opening direction. Further, the handle of the handle operating mechanism is in a state of being housed in the recess of the housing which is the mounting portion thereof. Thus, when it becomes necessary to open the window, the release mechanism is operated to release the engagement between the ratchet mechanism and the winding mechanism.
The restraint of the window is released, and the window is instantly opened by the self-weight and the biasing force. Then, when closing the window, the handle is pulled out from the concave portion of the housing and rotated about the second axis. At this time, the movable member moves outward in parallel along the first axis, but the rotating member and the winding mechanism are maintained in the connected state via the connecting member. Thus, similar to the handle operating mechanism described above, when the handle is rotated, only the movable member rotates, but after the movable member has rotated by a predetermined angle, the movable member and the rotating member become integrated via the restricting means. Rotate. As a result, the winding mechanism connected to the rotating member is rotationally driven and the wire is wound, so that the window is closed. After that, if the handle is rotated in the opposite direction by a predetermined angle and pressed toward the housing, the movable member moves in the direction of the housing, so that the handle is housed in the recess until it is flush with the surface of the housing.

Since it is on d and is prevented from moving toward the lid 9,
A fixed gap is held between the lever 71 and the lid 9. Therefore, the lid 9 is smoothly rotated without coming into contact with the surface of the lid 9. When the handle 70 is rotated counterclockwise and the movable member 60 is rotated by the predetermined angle with respect to the rotating member 50, the flange portions 63 to 65 are fitted in the gaps between the step portions 53d to 55d of the rotating member 50 adjacent to each other. Therefore, if the handle 70 is inverted 180 ° and pressed in the direction of the lid body 9 here, the handle 70 moves in the direction of the lid body 9 together with the movable member 60.
As a result, the handle 70 is attracted to the permanent magnet 77,
The accommodation state shown in FIG. 19 can be achieved.
